El empleo de las Sistemas de Información Geográfica (SIG) ha ido ganando terreno poco a poco, durante los últimos años, en la realización de la Encuesta de Infraestructura y Equipamientos Locales (EIEL). La transposición de la directiva europea 2007/02/EC para establecer una Infraestructura de Información Espacial en la Comunidad Europea (INSPIRE) ha hecho que las administraciones, tanto locales como estatales, busquen mecanismos para la publicación de los datos geográficos y en el caso de la EIEL no es una excepción. El auge de las nuevas tecnologías han hecho que poco a poco Internet esté presente cada vez más en nuestras vidas, convirtiéndose probablemente en el medio más utilizado y más ágil para la comunicación. Los Sistemas de Información Geográfica, consolidados ya en el escritorio, han ido también, de forma paulatina incorporándose a la nube, ofreciendo casi las mismas ventajas al almacenar, editar y compartir información. Las tecnología actuales más potentes están además, muchas de ellas, basadas en el Software Libre y evolucionan de forma extremadamente rápida. Pero, ¿es realmente necesaria siempre toda esta tecnología? ¿es necesario que los Sistemas de Información Geográfica abandonen por completo el escritorio para mudarse a la web? A través del análisis de los Geoportales que varias administraciones han creado para divulgar y compartir los datos obtenidos en la EIEL, en este documento se intentará dar respuesta a estas preguntas basándose en indicadores objetivos sobre la aplicación actual que se está haciendo de estas tecnologías

La Agència Valenciana de Turisme ha emprendido el proyecto de actualización de la web de promoción de la Comunidad Valenciana, el portal http://www.comunitatvalenciana.com. Este portal es una referencia internacional para todos los visitantes de la Comunidad Valenciana y por tanto un proyecto clave en su promoción turística. En esta ponencia se presentará la elaboración de un geoportal turístico atractivo y preparado para soportar un número elevado de visitas. En el contexto del proyecto se han abordado problemas como la visualización de información vectorial (puntos de interés) en un elevado número mediante la técnica de agregación o clustering. Por otro lado dicha información vectorial se procesa de tal forma que el visitante de la web obtiene un rendimiento en los tiempos de respuesta bastante elevado gracias al uso de técnicas de multirresolución en el visor web. La información de partida se migra a una base de datos espacial libre y se procesa para generar archivos en formato JSON. Por otro lado, el geoportal ofrece un flexible motor de búsquedas, preparado igualmente para soportar una carga elevada de peticiones mediante el uso de la indexación con el soporte para consultas espaciales. Este motor de búsquedas igualmente se ha preparado para utilizarse como servidor para ofrecer toda la información del portal a través de Layar, un servicio de realidad aumentada para móviles. Este servicio está completamente basado en componentes libres como el framework Spring o el soporte de búsquedas Lucene. Se presentará por tanto cómo se ha abordado la realización de una solución completa de presentación de información de un portal turístico de exigencias de rendimiento elevadas, centrando la atención en los componentes del servidor, todos ellos basados en software libre

The displacement of writing emerged in urban centers due to its investment in technology and has been developed in major newspapers around the world. With the advent of the internet and technological development, the writing went from analog to digital. That made it no longer required the presence of the journalist in the physical redaction means modifying the various management structures of a writing routine and professional. This happened to capture, edit and distribute your notes, news and reports in online mode. This monograph aims to understand and define the macro change of virtualization in journalism, considering the stages of production of Le Monde Diplomatique, a newspaper whose writing is in process of deterritorialization, the people involved in this activity and the resources used and contributing to the debate on new forms of organization of an editorial environment

Scientific research has shown remarkable advances in the formulation of criteria for assessing the quality of journalism practiced in the commercial media and public broadcasting, comprising aspects such as management models, business principles, parameters to the assessment of results and exercise of social responsibility. However, there are fewer investigations on the practice of journalism in digital public communication formats explored by government web portals. The contribution of this paper lies in a proposal of elements for the construction of parameters for evaluating the quality of journalism in the digital public communication. The proposal is inspired by criteria for evaluating the quality of commercial media and public broadcasting and suggests means for its application in the journalism practiced in the context of government web portals.

An expansion of the professional field of Public Relations can be seen nowadays, influenced by factors such as the increasing use of information and communications technologies for the dissemination of information on public management and the potential creation of dialogue between government and citizens. Despite this trend, there is still a need for specific knowledge about normative aspects of public communication generated by governments on the internet and its role in the fulfillment of the right to information. This article offers a contribution to fulfill the gap of guidelines and standards for professional performance. It describes the results of empirical research which identified the potential contribution of government web portals of the main cities of São Paulo, in the southeastern Brazil, to the strengthening of citizenship, considered in its dimension of exercising the right to information about public policies, particularly those which have an impact on education. The depth and breadth of information were investigated according with twelve categories of evaluation: history; diagnoses; goals; goals; resources and current actions; planned resources and actions; efficiency; effectiveness; impact; cost-effectiveness; user satisfaction; and equity. The data found on the analyzed portals correspond to the average of 11% of which was considered, under the theoretical-methodological context of the research, as information necessary to comprise the full characterization of a public policy in relation to the categories of assessment. Opportunities to improve government web portals were detected, for which we suggest communication management strategies.

Public communication comprises the dissemination of information on the various aspects of public management, with transparency and accountability, including the use of the existing technological resources. Particularly in the field of cultural policies, the right to information must be exercised as a contribution to political participation and economic expansion. This paper presents the results of research that was investigated, through analysis of the content under thirteen categories of evaluation, of the quality of information on cultural policies in web portals of the different spheres of government in Brazil. The results show the lack of information on the processes of development and implementation of policies in that field.

Maps have been published on the world wide web since its inception (Cartwright, 1999) and are still accessed and viewed by millions of users today (Peterson, 2003). While early webbased GIS products lacked a complete set of cartographic capabilities, the functionality within such systems has significantly increased over recent years. Functionalities once found only in desktop GIS products are now available in web-based GIS applications, for example, data entry, basic editing, and analysis. Applications based on web-GIS are becoming more widespread and the web-based GIS environment is replacing the traditional desktop GIS platforms in many organizations. Therefore, development of a new cartographic method for web-based GIS is vital. The broad aim of this project is to examine and discuss the challenges and opportunities of innovative cartography methods for web-based GIS platforms. The work introduces a recently developed cartographic methodology, which is based on a web-based GIS portal by the Survey of Israel (SOI). The work discusses the prospects and constraints of such methods in improving web-GIS interfaces and usability for the end user. The work also tables the preliminary findings of the initial implementation of the web-based GIS cartographic method within the portal of the Survey of Israel, as well as the applicability of those methods elsewhere.

Tenint en compte l’evolució a Internet dels portals d’informació dels mitjans de comunicació, sorgeix la idea d’un motor de cerca orientat a la recaptació de notícies dispersades per les diferents pàgines web dels grans mitjans de comunicació espanyols, que permetés obtenir informació sobre “descriptors contractats” pels usuaris d’un portal. El primer objectiu és l’anàlisi de les necessitats que es volen cobrir per a un hipotètic client de l’aplicació, el segon és en l’àmbit algorítmic, cal obtenir una metodologia de treball que permeti l’obtenció de la notícia. En l’àmbit de la programació es consideren tres etapes: descarregar les pàgines web necessàries, que es farà mitjançant les eines que proporciona la llibreria cUrl; l’anàlisi de les notícies (obtenir tots els enllaços que corresponen a notícies, filtrar els descriptors per decidir si cal guardar la notícia, analitzar l’estructura interna de les notícies seleccionades per guardar-ne només les parts establertes), i la base de dades que ens ha de permetre organitzar i gestionar les notícies escollides

Diferentes organizações públicas e privadas coletam e disponibilizam uma massa de dados sobre a realidade sócio-econômica das diferentes nações. Há hoje, da parte do governo brasileiro, um interesse manifesto de divulgar uma gama diferenciada de informações para os mais diversos perfis de usuários. Persiste, contudo, uma série de limitações para uma divulgação mais massiva e democrática, entre elas, a heterogeneidade das fontes de dados, sua dispersão e formato de apresentação pouco amigável. Devido à complexidade inerente à informação geográfica envolvida, que produz incompatibilidade em vários níveis, o intercâmbio de dados em sistemas de informação geográfica não é problema trivial. Para aplicações desenvolvidas para a Web, uma solução são os Web Services que permitem que novas aplicações possam interagir com aquelas que já existem e que sistemas desenvolvidos em plataformas diferentes sejam compatíveis. Neste sentido, o objetivo do trabalho é mostrar as possibilidades de construção de portais usando software livre, a tecnologia dos Web Services e os padrões do Open Geospatial Consortium (OGC) para a disseminação de dados espaciais. Visando avaliar e testar as tecnologias selecionadas e comprovar sua efetividade foi desenvolvido um exemplo de portal de dados sócio-econômicos, compreendendo informações de um servidor local e de servidores remotos. As contribuições do trabalho são a disponibilização de mapas dinâmicos, a geração de mapas através da composição de mapas disponibilizados em servidores remotos e local e o uso do padrão OGC WMC. Analisando o protótipo de portal construído, verifica-se, contudo, que a localização e requisição de Web Services não são tarefas fáceis para um usuário típico da Internet. Nesta direção, os trabalhos futuros no domínio dos portais de informação geográfica poderiam adotar a tecnologia Representational State Transfer (REST).

We describe ncWMS, an implementation of the Open Geospatial Consortium’s Web Map Service (WMS) specification for multidimensional gridded environmental data. ncWMS can read data in a large number of common scientific data formats – notably the NetCDF format with the Climate and Forecast conventions – then efficiently generate map imagery in thousands of different coordinate reference systems. It is designed to require minimal configuration from the system administrator and, when used in conjunction with a suitable client tool, provides end users with an interactive means for visualizing data without the need to download large files or interpret complex metadata. It is also used as a “bridging” tool providing interoperability between the environmental science community and users of geographic information systems. ncWMS implements a number of extensions to the WMS standard in order to fulfil some common scientific requirements, including the ability to generate plots representing timeseries and vertical sections. We discuss these extensions and their impact upon present and future interoperability. We discuss the conceptual mapping between the WMS data model and the data models used by gridded data formats, highlighting areas in which the mapping is incomplete or ambiguous. We discuss the architecture of the system and particular technical innovations of note, including the algorithms used for fast data reading and image generation. ncWMS has been widely adopted within the environmental data community and we discuss some of the ways in which the software is integrated within data infrastructures and portals.
